It will fit any of the old Specto projectors and will probably be ok for all guages - STD 8, 9.5 and 16mm. Depending on the size of the rear glass. You have a Specto I believe, so why not try it.

The traditional shape Specto projectors were made for three separate gauges, 8mm, 9.5mm and 16mm, (and dual-gauge models), therefore they also had three different focal lengths to match.Their lenses were, 1", 1.5", and 2".

Which gauge do you think it was intended for Maurice/Terry ?The back lens is only 9mm, I just tried it with 9.5 & it gave a bigger picture which somewhat surprised me although I can't imagine it will be any good for 16mm

I too have Specto projectors,a 9.5mm and a Standard 8mm and they look identical apart from the gate etc.I tried using my 8mm lens in my 9.5mm and it did give me a much bigger picture,but to me,it wasn't as sharp,so I put it back in my 8mm.That info was probably "old news" haha

VicIt looks like the one you have is a 1" which does give a bigger picture and I use it for 9.5mm because of that and I find it gives good definition too. I have also used it on a Bell&Howell 1698 16mm projector (with a sleeve) and it gives a nice big picture but you do suffer a little vignetting because the rear glass is too small for 16mm.
